Application 11.1.1 na 19.1919. sw rms. asaacc To allwhom'itmayconcem: I

Be it known that 1, CHARLES C. Nnenn, citizen of the United States,residin at St. Paul, in the county of Ramsey and tate. of Minnesota,have invented certainnew and useful Improvements in Liquid-DispensingApparatus; and I do hereby declare the fol lowing to be a .full,'clear,' and exact descri tion of the invention, such as will enab eothers skilled in the art to which it appertains to make and use thesame,

My invention relates to liquid measuring apparatus, andfor itsparticular object, has" the provision of a simple, very accurate andgenerally eflicient apparatus for measuring of asoline, kerosene, .andthe hke, at 011 ven ing stations.

' Generally stated,the invention consists in the novel devices andcombinations of de-- vices hereinafter described and defined in theclaims.

The vending tanks used at oil stations are usually about ten inches indlameter, so.

that in altitude, each gallon represents less than three inches. Anymeasuring instrument not showing reater movement than three inches pergal onwill not give the reuired accuracy in reading, and, in fact, theQlnited States Bureau of Standards, in their proposed s ecifications forvisible reading measuring evices, have suggested that units of gallonsbe represented on indicating scales by at least four inches of linealmeasurement or distance.

As one important feature, my invention provides simple means wherebythis multiplied or increased indicator movement may able sheave or guidewheel on the top of the tank, is connected to a wheel or cylindrical rimof an indicator drum or wheel having a graduated face of materiallylarger diameter than the rim thereof upon whlch drum extendcircumferentially thereof, and the dls tance between marks indicatinggallons W111 be represented b lineal dimensions much greater thanthedistance traveled'by the float or by the upper surface of the llqllld inthe tank. The drum is, of course,

outside of thetank, and it is under yielding strain to rotate in adirection to take u the slack of the cable. The float has $11 c 1entwelght to rotate the drum in the opposite direction. The indicator drumis a sort of differential drum-with the operatin cable attached to andadapted to be woun upon its smallest diameter or section.

The liquid containing tank 6xmay be supported by any suitable means, asby a pedestal 7 The liquid may be supplied to the bottom of the tankthrough a valve-equipped pipe 8 and may be drawn off from the tank froma point bottom throug pipe 9. The tank, at its top, is provided with asecured head 10 which, at the axis of referably slightly. above the thetank, is formed with a valve seat 11 a valve-equipped vending,

having a central pa$age 12. Working within the tank and riding upon theliqui therein contained, is a float 13 which, on 1ts top, carries avalve 14 shown as a semispherlcal form and adapted to fit the seat 11when the float is raised to an extreme position. .The float 13 isattached to the inner end of a cable 15 shown as inthe form on thesurface of the liquid within the tank.

Of course, the natural floating action of the host 13 is modifiedsomewhat by the counter i all ofa link'chain, and this cable is passed 7cable 15, but afl'ords a normally open vent,

freely upward through the passage. 12 and over a guide sheave 16 that isjournaled to a bracket1 7 on the tank cover or head 10.

As will hereinafter more clearly appear, the

assage' 12 not only serves as a passage for from the top of the tank tothe atmosphere,

' which, nevertheless, is adapted to be closed V the tank with oil, orrunning of oil through when the float is raised to an extreme position,and thereby prevent overflowing of r the top of the tank.

" The 'outerlower end of operative cable 15 is attached to and adaptedto be wound upon the cylindrical flange or a smaller portion 18 f V of fthe indicator drum 19. 1 This indicator drum is rotatively mounted onthe spindle 20 shown as secured to and projecting horizontallyfromclamping bands 21 that embrace the tank 6. ';The indicator drum ismounted within a casing or housing 22 that {1s also fixed to theanchoring straps 21. In

'7 its top, the housin 22 is provided with a freelyand, in its bottom,it is provided with passagethrough'w ich the cable '15 works apassagethrough which another cable, pref erably 1n the form of a flat chain 23,works I freely; The upper-fend of the chain 23 is attached to and workson a small wheel or drum flange 24 attachedto, or otherwise car- 7 riedbythe indicator drum. At its lower end, chain23 1s provided'with aweight 25 which J operates with a constant yielding force that tendstorotate the drum in a direction reverse to the direction in which it isrotated by the 'weight'of the float 13. Hence, of course, the float/13must be heavy enough to overcome and raise the Weight 25, but must havesuliicientbuoyancy to cause the same to float action of the weight 25,but the, float'will maintain a constant position in respect to thesurface of the liquid throughout the rising and falling of the liquid inthe tank;

As shown in Figs. 2 and 4, the numerals,

towit, the digits and fractions located at the left, together with theassociated scale lines, indicate liquid quantities, towit, gallons andfractions thereof. These quantity or gallon 'indicatin marks, including,:of course, the

fractiona marks, may be located by actual tests with standard'measuresso that they 7 will thereafter positively and accurately in dicate exactmeasures. 7

The housing 22, at the front thereof, is

I provided with a transparent reading passage 26 7 through which thequantity measurements on the drum may be read; and to insure accuracyinreading, the casing is provided with a pointer 27 with which thecircumferential quantity indicating lines 28 of inoaoec tity, but totalselling price of any given quantity at a given price, within-the rangeof the scale, may be instantly read.

In practice it will be advisable to entirely incase the cables 15 and,23, sheave 16' and weight 25 so that, in the first place, it may not betampered with, and in the second place, will be protected fromweatherconitions. Measuring apparatus well as various other kinds, are,in practice, tested and sealed by either State or municial weights andmeasurino departments, and

of this character, as

it is highly important therefore that they be of such character thatthey "cannot be tampered with or their accuracy destroyed withoutdetection by the ordinary observer. In this device accuracy can onlybedestroyed by defacement of the scale reading which would be a parent toanyone.
